Cryopreservation (freezing)

Cryopreservation is a process by which cells or whole tissues are preserved by cooling to sub-zero temperatures, typically -196°C. At these low temperatures, biological activity, including the biochemical reactions that lead to cell death, is effectively stopped.

The process is ideal for sperm and embryos and, since the introduction of vitrification (a process which minimises damage due to ice crystal formation), eggs can also be cryopreserved to achieve a higher chance of success.

Bridge provides a comprehensive range of services for people who, for medical or social reasons, wish to preserve eggs, sperm or embryos for possible future use.

We are pleased to offer:
• Sperm cryopreservation and storage
Egg freezing and egg storage
• Embryo cryopreservation and storage for patients with surplus embryos after IVF/ICSI
• Freeze and Share – an innovative programme which enables women to donate some of their eggs and freeze the remainder
